I have the latest version of HP tuners and I'm going to be upgrading from my 2.73 rear to a 3.42 rear. What all do i need to tune? Under the "Speedometer" category i can see where i can change my gear ratio and click commit (as well as auto scale my A4 tables) is this all that I'm gonna have to do to have my correct shiftpoints, etc??? anywhere else I'm gonna have to go and change something? thanks for the help

thats up to you really but generally the auto scale feature does the work for you...theres always room for tweaking though.

good, so basically just changing the gear ratio and commiting with the autoscaling will be about 95% of what I have to do.

it'll be 100% of what you need to do but about 80% of what you should do
